IMPROVEMENT iIN THE PREPARATION OP ALBUMEN.

Be it known that I, Gus'mvn Bouuoanufof the city and State of New York, have invented an Improvement in the Prepai-ation of Albumen; and the following is declared to be a correct description of the some. a In the manufacture-"of albumen, by the processes heretolbre in use, the albumen was nbt.;eiitirely.e

true-ted from the blood, and many impurities passed outset the blood with the albumen, asitai'as allowed vwtofcoagnlating ,ontalned :lhuthe.

Itake blood, either after ihhas been subjected to the fiu'egoing operatiou or in its usual condition, and add about ten per cent. of alkali, such as slaked lime, and also about twenty-five per cent. of water. The mass is thoroughly stirred, and then put into asuitable still or evaporating vessel, by means of which the water added, or a portion thereof, may be c vaporated at as low a temperature as convenient. v

The vapor may be condensed, and contains traces of ammonia.

The mass remaining is of a spongy character, the

"coloring matter, fibrin, and other substances, except the albumen, being sulfieiently acted upon by the 'alkali to be retained in a mass, while the albumen is extract-ed by mechanical force, such as pressure in any suitable press, atmospheric pressure, or filtration into fan exhausted receiver, or a centrifugal drying appara tus, the albumen being received in a liquid state and of a very good quality. I

. The liquid albumen may be conoentrated, by evaporation, in a vacuum, and then exposed in shallow pans for drying.

, 'lheiiine may be mixed with the bloodat the slaughter-house, and then barreled for shipment, so as toaid in preserving said blood from decomposition previous to the other operations described.

I-clailn as my invention- The process, substantially as herein specified, for separating albumen ti-oin blood.
